چکیده
This paper presents five SIMULINK libraries for modeling, design, optimization and testing of digital protective relays. The new MATLAB based software package includes the following libraries: Relay Elements, Relays, Protection Systems, Input Signals and Tools. The paper presents the software package in detail. First, all the components are described including their functions and variety of available options. Next, sample studies are presented illustrating the usage of the package to simulate operation of digital relays in both open-loop and closed-loop modes.

Real-time implementation of digital relay models using MATLAB/SIMULINK and RTDS
Software models for protective relays offer an economic and feasible alternative to studying the performance of protective relays. Relay models have been long used in a variety of tasks, such as designing new relaying algorithms, optimizing relay settings and training personnel [1]. In order to be practical, software relay models must reproduce the actual operation of the physical relays. This ...
متن کاملThe Effect of Conventional Instrument Transformer Transients on Numerical Relay Elements
Current and voltage transducers provide instrument level signals to protective relays. Protective relay accuracy and performance are directly related to the steady state and transient performance of the instrument transformers. Protective relays are designed to operate in a shorter time than the time period of the transient disturbance during a system fault. Large instrument transformer transie...

This with the integration of distributed generation (DG) to meshed distribution systems, the operating time of the protective system becomes a major concern in order to avoid nuisance DG tripping. This paper proposes a new tripping characteristic for directional overcurrent relays (DOCRs) that can achieve a higher possible reduction of overall relays operating time in meshed distribution networ...
متن کاملA Combined ANFIS and Wavelet Transforms Approach for Power Transformer Protection
This paper presents a new approach for classifying transient phenomena in power transformers, which may be implemented in digital relaying for transformer differential protection. Discrimination of various operating conditions of the power transformer is achieved by combining wavelet transform with Adaptive Neuro Fuzzy Inference system (ANFIS). The wavelet transform is applied for the analysis ...
